Örkelljunga heating plant

Background:

Örkelljunga Fjärrvärmeverk AB is owned by Örkelljunga municipality and was founded in the 1980s. The plant consists of two boilers of 7 and 3.5 MW, respectively, which burn forest chips and residual products from forestry. To reduce its electricity and grid costs and at the same time contribute to reducing the power shortage in southern Sweden, Örkelljunga district heating plant chose to invest in an ORC turbine from Againity.

Our solution:

Againity delivered an automated ORC system with a maximum capacity of 250 kW electricity production. The ORC system enables electricity production from the boiler’s hot water. In total, the system is expected to produce 1000 MWh of electricity annually, corresponding to annual emission savings of 900 CO2 equivalents substituting coal-based electricity. Örkelljunga district heating plant has chosen to sign a service agreement with Againity to ensure a long service life and minimal maintenance.
